Synthesis of Information Related to Highway Problems. Topic 45-13. Maintenance Quality Assurance Field Inspection Practices

Maintenance Quality Assurance (MQA) is a business practice that has increasingly been adopted by the maintenance professionals of many state transportation agencies, toll highway authorities, private sector road maintainers and various counties and cities since the 1990s. MQA programs are performance- and outcome-based programs that help measure and report on the condition of highway assets, linking results to budgets and providing managers with program measurements. Performance standards and goals of these programs vary based on state geography, population, and customer expectations. Key to this topic, National Cooperative Highway Research Program (NCHRP) published a Maintenance Quality Assurance Program Implementation Manual (NCHRP Report 422) in 1999. Since then, various efforts have been made to bring state agencies together to investigate current practices related to MQA; including national peer exchanges in 2004 and 2008, and a U.S. Domestic Scan (10-03) in 2011 entitled: "Current Practices in Performance Measuring for Highway Maintenance and Preservation." This synthesis will build upon the information shared through those activities. The objective of this synthesis is to document current practices of MQA programs and MQA inspection processes that are administered within the maintenance organization of state transportation agencies. The information will be beneficial to transportation agencies that are considering implementing a new maintenance inspection regimen or revising existing practices. Information documented by this synthesis will include, but is not limited to, the following: (1) Scope of the agency's MQA program (e.g., when implemented, program objectives, assets assessed, assessment criteria); (2) Inspection process (e.g. frequency, in-house or outsourced personnel, training, sample size, data collection methodology); (3) Quality assurance for MQA data (e.g., process, outcomes, data quality and consistency); (4) Use of MQA data (e.g., analysis, business decisions, access, communication, budget, maintenance contract compliance, performance standards); (5) New initiatives and technologies agencies are considering to improve their MQA programs; and (6) Rationale and motivation related to MQA development and implementation will be explored in follow-up interviews and case examples developed for the synthesis. Information will be gathered by literature review, survey of state departments of transportation (directed to the American Association of State Highway and Transportation Officials (AASHTO) Highway Subcommittee on Maintenance), and follow up interviews for selected case examples.
